Developing a python project on the platform and attempting appengine endpoints.
import endpoints throws google.appengine.api.yaml_errors.EventError: the library "endpoints" is not supported. The full stack trace is below.

Start with a non-python project.
Download appengine for Linux python:
curl -O http://googleappengine.googlecode.com/files/google_appengine_1.8.9.zip
Unzip and export directory in ~/.bash_profile:
export PATH="$HOME/google_appengine:$PATH"
Build endpoint python app as described and run dev_appserver.py.
You can't view the Google APIs Explorer when launched from Nitrous.io, unless you port forward, but you can still use as a developing endpoint.

Trying to set up static assets on a Pyramid app. I used the following call:
config.add_static_view(name='static', path='toolsofknowledge:static')
The file main.css is stored under toolsofknowledge/static/main.css, as expected. The toolsofknowledge package is installed locally with an editable link, using pip3 install -e ..
Requesting http://localhost:8080/static/main.css with curl causes this exception on the server:

Python 3.7, Pyramid 1.10.2.
Solution: add __init__.py to toolsofknowledge directory.
The problem is quite simple -- the toolsofknowledge package was not a real package, despite being installed, as it was missing an __init__.py. This causes toolsofknowledge.__loader__ to be an instance of NamespaceLoader, when it should be SourceFileLoader. Obviously, pkg_resources cannot resolve resources relative to something that's not a real package. Arguably it should handle this case more smoothly though.
I have the following python program on Python 2.7 that uses python WDSL library.
>>> from SOAPpy import WSDL
>>> wsdlFile = 'my_wsdl_file_path'
>>> server = WSDL.Proxy(wsdlFile)
And I get below error;
Traceback (most recent call last):

what could be the reason?
My experience with SOAPpy is that it is not as complete nor tolerant as Suds. Maybe you should try parsing your WSDL file with suds instead.
import suds.client as client
session = client.Client('file:///absolute/path/to/yourwsdl')

socket.error: (101, 'Network is unreachable')
This is ok, because this host does not have access to the internet but has access via http proxy. But i can't find anything how to configure pysetup for http proxy.
I already tried exporting the proxy variables wget/curl style:
http_proxy=http://proxyhost:3128
HTTP_PROXY=http://proxyhost:3128
https_proxy=http://proxyhost:3128
HTTPS_PROXY=http://proxyhost:3128
Any idea?
I upgraded my GAE SDK to Version 1.8.5 and cannot generate a discovery file anymore with endpointscfg.py gen_discovery_doc -o.-f rpc .../main.FlyFlap.APi
I get the errors below.
I tried to delete the file google_appengine/lib/cacerts/urlfetch_cacerts.txt and certs.txt like it is suggested here, but it didn't help. Does someone got same problems?

Google App Engine won't start due to errors. The information below is from the error log file created by the app engine. How can I fix this?
